My invention relates to filling and venting devices and particularly todevices of the kind described that are adapted to be mountedl inbarrels,metallic drums, or the equiv? alent. v

The invention has among its other objects, the production of devices ofthelrind described that are compact, convenient, durable, eiiicient andsatisfactory for use wherever found applicable.

An object of theinvention is to provide an improved closure member forthe lling opening of a barrel or the equivalent, which closure memberisadapted to permit removal of aV portion thereof for-filling the barrel,the portion remaining being constructed to serve as a lire bafHe suitedto withstand usage incidental to inserting `a tube Vor thelike in thebaille for filling.

Still'anotherobject is the provision' of an improved venting deviceadapted toH be mounted upon a barrel orv the'A equivalent, which' iscapable of functioning as a venting device regardless ofv where it v.islocated in the barreLand also regardless ofthe position of the barrel. g

lA particular objectfof the invention fis to provide ank improved llingand venting de-V vice which maybe mounted upon a barrel, or theequivalent, in such manner that it will not interferewith the handlingthereof'.

Another particular object of the invention is to provide anrimpro'vedventingdevice adapted to be mounted upon a barrel, or the Y equivalent,and constructed so that it may be readily adjusted to admit air 4intothe barrel when the barrel is being emptied.

` Still another particular object of the invention is toprovide animproved ,closure memberl fort-he filling lopening of a barrel, or theequivalent, which closure member is adapted to permit the escape ofgases from the barrel when the pressure ther/einy rises to apredetermined value, Y Many other ,objects and advantages of theconstruction herein shown and described'will be obviousV to thoseskilled in the artffrom the'dis'closure herein given; rIlo this endA myinvention vvconsistsin` the 50 novel construction, Aai'ra"ngementand'c'ombination of parts herein shown and described,

andV more claim.

In the drawings, wherein like reference characters indicate like orcorresponding parts: v f

Fig. 1 is a perspective view of a metallic barrel or drum upon which adevice embody# ing my invention has been installed;

Fig. 2 is an enlarged section vtaken on line 2 2 of Fig. 1;

particularly pointed out in the Fig. 3 is a section taken online 8-*3 ofFig.

2; andl f o Fig. 4E is a' section taken on line 1- 4 of Fig. 2; v 'YWhile my improveddevice isfshown and described in connectionV with 'ametallic bar-VV rel or drum, itis to be understood Athat my inventionis'limited to this use only tothe extent indicated inthe appended claim.Referring to Fig'l, the reference character l0 designatesgenerally Yafilling and venting device which embodies aV preferred form of theinvention and is installed upon'a metallic barrel orv drum whichVisdesig'n'ated bythe referencefcharacter 11. `The drum 11 is -ofwell'known construction and is substantially cylindrical in form. Inlinewith thev construction generally jemployed in -connection with drumsor barrels of this type, the drumY 11 is provided with a plurality ofannular beads 12 upon which the drinn may be rolled.` In this instance,lthe iillin'gopening of the barrel` 0r drum 11 is disposed intermediatethe beads 12 but it willbe `noted' that theimf provedlling andV ventingdevi-ce 10 may be mounted in the illingopening of the drum no matterwhere theiilling opening is located upon the drum. However, "my improvedfilling and venting device is particularly advantageous when itismounted in thecylindrical WallVV of a drumlorlbarrel ofthe type shown inFig. 1. n Referringto Fig. 42, the 'cylindrical'wall of the drum orbarrel 11 is designated by the reference character 15 kand thel filling'opening thereinis designated by thereference character 16. Mounted inthe iillingopening 16 and rigidly secured to the wallfl is a collar 18.Screw-threadedinto the collar18 and projecting into the barrel 11 isv anannular member 19, the annular member 19 being provided with externalscrew-threads adapted to engage internal screw-threads formed upon thecollar. The annular member 19 is also provided with internalscrew-threads adapted to engage external l'screw-threads provided upon aboss 21 which form part of a plug 22, the plug 22 being adapted to beremoved from the barrel whenever 'the barrel is to be filled. Theannular member 19 is provided with a vdownwardly extending integralannular flange 23 provided with internal screw-threads which lareengaged bymenternal v screw-threads provided up'ona metallic ring' 2 4to which a foraininous tube 25 is secured. The foraminous tube'2`5 ispreferably pro-` vided with flame-proof apertures throughout its entirelength and its lower end is preferably closed by a plate 27 which is'also preferably provided with flame-proof apertures. Resting upon theplate 27 is the bottomend of a tubular member 29, which is provided witha plurality of apertures 30,. rllhe apertures Jare preferably formed inthe lower end of the tube 29 and are preferably larger than theiameproof -aperturesprovided in the tube 25. The lower end of the tube29 is preferably closed Yby an apertured plate 32. The tube 29 and theplate 32 are preferably formed from thicker Ysheet metal than the tube25 and its bottom plate 27 so that the tube29 and the plate 32protectthe tube 25 and its plate 27 when sticks, filling nozzles, or thelike, are inserted in the barrel through the filling opening thereof.yYAnother advantage of this construction is that the tube 29 protects thetube 25 in the event that an explosion occurs Within the tube 29. Thus,assuming that 'an explosion occurs vin thetube 29, it is readilyunderstood that the lgases resulting from the `explosion will passIthrough the apertures -30 but the pressure thereof will be reduced tosuch an extentthat the tube v25 will not be subjected to the .full forceof the explosion. The upper end of the tube .29 is preferably iared asVat and preferably engages an annular :groove 36 formed in the bottomsurface of the -annular member 19. Y

It will be noted that the tubular member `29 is disposed concentricallywith respect to the tubular 'member 25 andthat :its wall is spaced fromthe tubular member 25 to provide an annular passage v38 which extendsfrom the l bottom .of the -tubes up to the upper ends thereof. The upperend of the annular passage 38 communicates with the lower ends of aYplurality of vertically extending apertures or passages 40 formed inthe annular member 19.. Resting upon the upper sur-face of the annularmember 19 :and interposed -between that memberand the -pl-uO 22 isagasket 42 which is preferably made of? some suitable material suchv asleather,'-or the equivale-nt. Obviously, if the plug 22 and thegasket'42are removed from the barrel, and funnel or nozzle is inserted in theopening for filling the tank, gases may flow from the annular passage 38up through the passages or apertures 40 and thence into the atmosphere.

Slidably journaled in the plug 22 is a vertically disposed pin or valvestem 44 which, at its upper end, carries a disk or valve 45. Alsocarried by the pin or valve stem 44 is an apertured gasket 47 formedfrom leather, or the equivalent, the gasket being adapted to seat uponan annular shoulder 48 formed in the bottom of a recess 46 provided inthe plug 22. A compression spring 50 disposed around the pin or valvestem 44 and interposed between the plug Y22 and cast-le nut 51 carriedby the valve stem yieldingly holds the gasket 47 in engagement with theseat or shoulder 48. Formed in the plug 22 Within the boundaries of theannular seat or shoulf der 48 are Aa plurality of ports or vents 54through which gas may escape from the barrel when the gasket 47 isdisengaged from the shoulder 48. Obviously, the spring 50 may beadjusted to permit the escape of gas from the barrel when apredetermined pressure obtains therein.

It will Ybe noted that the recess 46 is of sutlicient depth so that theupper surface of the valve 45 normally lies beneath the upper surface ofthe plug 22 and that the gasket 47 may be disengaged from the .shoulder48 without bringing the upper surface of the valve 45 above the uppersurface ofthe plug.

This is advantageous in that when the barrel is in a position whereinthe plug contacts or substantially contacts the surface upon which thebarrel is supported, the valve 45 may be displaced tojallow -a reductionin the pressure within the barrel. The plug 22 preferably projects arelatively small distance from the barrel so that it will not be injuredwhen the barrel is rolled along 'upon its beads 12. n

When the barrel is to be filled with liquid, the plug 22 and the gasket4 7 are preferably removed from the annular member 1-9 so that theliquid may be poured into the barrel or a nozzle maybe inserted in thetube 29 to discharge the liquid therein. The air displaced in the barrelthen passes through the 4annular passage v38 and thence through theapertures 40. When the contents of the bar-rel are to be removedtherefrom, the plug 10b is removed .from the screwthreaded opening 10aand a faucet (not shown) lis inserted therein. The plug 22 is unscreweda few turns so that the gasket 42 does not seal the upper ends .of theapertures 40. Obviously, when the faucet is opened to permit the liquidto escape from the barrel, air may' enter through the apertures 40 sothat lthe contents of the barrel can Vbe quickly discharged through thefaucet. Y

Having thus Vdescribed my invention, it is obvious that variousimmaterial modifications may be made Vin the same without departing fromthe spirit of my invention, hence I do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described, or usesmentioned.

What I claim as new and desire to secure by Letters Patent is:

In a device of the class described, a pair of foraminous tubular membersclosed at one end and telescoping each other with a space therebetween,means engaging the open ends of said tubular members and adapted toclose a tank or the like, said means having a flange forming a recess,said means also having a perforation therein, and a valve vseated insaid recess, said valve having a face yieldingly seated over saidperforation and adapted to be unseated upon the exertion of apredetermined pressure on said face, the depth of said recess beinggreater than the maximum movement of said valve.

In testimony whereof, I have hereunto signed my name.
